PaRaDe: Passage Ranking using Demonstrations with Large Language Models

no code implementations22 Oct 2023 Andrew Drozdov, Honglei Zhuang, Zhuyun Dai, Zhen Qin, Razieh Rahimi, Xuanhui Wang, Dana Alon, Mohit Iyyer, Andrew McCallum, Donald Metzler, Kai Hui

Recent studies show that large language models (LLMs) can be instructed to effectively perform zero-shot passage re-ranking, in which the results of a first stage retrieval method, such as BM25, are rated and reordered to improve relevance.

Rank-LIME: Local Model-Agnostic Feature Attribution for Learning to Rank

no code implementations24 Dec 2022 Tanya Chowdhury, Razieh Rahimi, James Allan

In this work, we extend LIME to propose Rank-LIME, a model-agnostic, local, post-hoc linear feature attribution method for the task of learning to rank that generates explanations for ranked lists.
